	Earth Aurora Animations - NASA/MSFC/CXC/A.Bhardwaj & R.Elsner, et al.; Earth model: NASA/GSFC/L.Perkins & G.Shirah Sequence of Chandra Earth Aurora Images. MPEG The bright arcs in this sample of Chandra images show low-energy X-rays (0.1 - 10 kilo electron volts) generated during auroral activity. The images are approximately 20-minute scans during which Chandra was pointed at a fixed point in the sky and the Earth's motion carried the auroral regions through the field of view. The estimated altitude of the X-ray emission is 100 km... Keywords: What -- Earth; What -- Polar Downloads: 79
	Saturn Animations - NOAA/SEC GOES-12 Time-lapse Movie of Solar Flare. MPEG The groundbreaking first observation of X-rays from Saturn's low-latitudes by Chandra appeared as a direct response to this solar event captured by the GOES Solar X-ray Imager. This solar flare is classified as an M6 - meaning it is medium-sized with the potential to cause brief radio blackouts at Earth's polar regions.
